When it may not be suitable

This terminal block is not intended for use with flexible conductors that require ferrules unless specifically rated for such applications. It is also not suitable for high-vibration environments where spring-loaded terminals might be preferred to maintain constant pressure.

Key specifications

• Conductor compatibility: Aluminum and Copper
• Connection type: Screw terminal
• Mounting: DIN rail
• Color: Brown

How to use

To install the Simet STB 185, mount the block onto a standard DIN rail until it clicks into place. Strip the insulation from the conductor according to the required length, ensuring the wire surface is clean. Insert the conductor into the terminal opening and tighten the screw using an appropriate screwdriver to the specified torque. Verify that the connection is secure by gently pulling on the wire.

What to consider before purchase

• Ensure the conductor cross-section matches the terminal capacity
• Verify the compatibility of the conductor material with the terminal block
• Check the available space on the DIN rail for installation

Usage recommendations

Always use a calibrated torque screwdriver to ensure the screw is tightened to the manufacturer's recommended specifications to prevent damage to the conductor or the terminal block.
